Disclosed is a method for producing a superconducting wire (1) having a filament portion (2) containing a Bi2223 phase and a sheathe portion (3) covering the filament portion (2). This method is characterized by comprising a filling step, a wire drawing step, a rolling step and a sintering step, and further characterized in that the filament portion does not contain a Bi2223 phase before the sintering step.
Cette invention se rapporte à un procédé de production d~un câble supraconducteur (1) comprenant une portion de filament (2) contenant une phase Bi2223 et une portion gainée (3) qui recouvre la portion de filament (2). Ce procédé se caractérise par une étape de remplissage, une étape d~étirage du câble, une étape d~enroulement et une étape de frittage ; elle se caractérise également par le fait que la portion de filament ne contient pas de phase Bi2223 avant l~étape de frittage.
